What is an opportunist?

An "opportunist" is a population (fungi, bacteria, insects…) that takes advantage of a favourable environment to settle in, multiply and feed on it. It often develops when the natural defences of the affected organism are weakened — for genetic reasons or linked to context (water stress, deficiencies, nutritional imbalances, overcrowding…). This is typically the case in monocultures, where a single host plant, uniform and present in large numbers, offers ideal ground for it to spread.

Identification key : Vascular wilts (fungi and bacteria of the vessels) (Damage and symptoms on the host)

Scientific name : Fusarium oxysporum f. sp. albedinis

Other names : Fusarium wilt of date palm

Form of Fusarium oxysporum specific to date palm, present in Morocco and Algeria, where it has destroyed millions of palms since the late 19th century. It enters through the roots and moves up the vessels: fronds dry one after another from the centre of the crown, with one side bleached, until the tree dies.

Crops affected : Date (Date palm)
